Mozilla Bans Popular YouTube Unblocker Add-On
Bohs Hansen / 5 years ago
One of Firefox’s popular add-ons has been kicked from the repository after repeated bad behavior, and it is unlikely to come back. The YouTube add-on uses a list of proxy servers to circumvent geoblocking of YouTube videos, which in itself is a very useful feature, but one that you’ll have to find another add-on for from now on.
The latest of multiple issues with the popular browser add-on that already accumulated over 250 thousand downloads started last weekend with a user reporting an issue on the Mozilla bug tracker. After installing the add-on, his anti-virus software alarmed him right away that it had blocked a download coming from a third-party website which had been flagged as malware by Avast Anti Virus.
On further examination, the user found out that the add-on was altering the browser settings and disabled the add-on signing feature preventing unauthorized installs, AKA add-ons that haven’t been signed or certificated by Mozilla. After disabling this security feature, the YouTube Unblocker add-on then went on to download another add-on called Adblock Converter from a third-party domain via an unsecured connection, an add-on that is categorized as malware and isn’t to be found in the official add-on library. To make matters even worse, users without proper anti-virus or anti malware solutions wouldn’t even know that this extra add-on was installed as it wouldn’t show up in the about:addons page either and it would reinstall itself again if a user managed to uninstall it in safe mode.
This is far from the first time that this add-on has been under investigation for bad behavior, last time in June 2015 where they were caught circumventing the official guidelines for add-ons with update code that bypassed the official Mozilla review process. Before that, they were caught tampering with search results and sending data back to the company without the users consent or knowledge, even when the user opted out of the feature.
Luckily for users who need a geo-unblocking feature for their Firefox browser, there are plenty of other alternatives to choose from.
